29 CFR § 553.21 - Statutory provisions.
Section 7(o) provides as follows:
(1) Employees of a public agency which is a State, a political subdivision of a State, or an interstate governmental agency may receive, in accordance with this subsection and in lieu of overtime compensation, compensatory time off at a rate not less than one and one-half hours for each hour of employment for which overtime compensation is required by this section.
(2) A public agency may provide compensatory time under paragraph (1) only -
(A) Pursuant to -
(i) Applicable provisions of a collective bargaining agreement, memorandum of understanding, or any other agreement between the public agency and representatives of such employees; or
In the case of employees described in clause (A)(ii) hired prior to April 15, 1986, the regular practice in effect on April 15, 1986, with respect to compensatory time off for such employees in lieu of the receipt of overtime compensation, shall constitute an agreement or understanding under such clause (A)(ii). Except as provided in the previous sentence, the provision of compensatory time off to such employees for hours worked after April 14, 1986, shall be in accordance with this subsection.
(A) If the work of an employee for which compensatory time may be provided included work in a public safety activity, an emergency response activity, or a seasonal activity, the employee engaged in such work may accrue not more than 480 hours of compensatory time for hours worked after April 15, 1986. If such work was any other work, the employee engaged in such work may accrue not more than 240 hours of compensatory time for hours worked after April 15, 1986. Any such employee who, after April 15, 1986, has accrued 480 or 240 hours, as the case may be, of compensatory time off shall, for additional overtime hours of work, be paid overtime compensation.
(B) If compensation is paid to an employee for accrued compensatory time off, such compensation shall be paid at the regular rate earned by the employee at the time the employee receives such payment.
(4) An employee who has accrued compensatory time off authorized to be provided under paragraph (1) shall, upon termination of employment, be paid for the unused compensatory time at a rate of compensation not less than -
(B) The final regular rate received by such employee, whichever is higher.
(A) Who has accrued compensatory time off authorized to be provided under paragraph (1), and
(B) Who has requested the use of such compensatory time, shall be permitted by the employee's employer to use such time within a reasonable period after making the request if the use of the compensatory time does not unduly disrupt the operations of the public agency.
(6) For purposes of this subsection -
(A) The term overtime compensation means the compensation required by subsection (a), and
(B) The terms compensatory time and compensatory time off means hours during which an employee is not working, which are not counted as hours worked during the applicable workweek or other work period for purposes of overtime compensation, and for which the employee is compensated at the employee's regular rate.
